Clear $db

[محروم.كوم]

I've started moving servers and upon trying to login to my admincp I get the following error:

Warning: mysql_connect() [function.mysql-connect]: Can't connect to MySQL server on '(removed)' (4) in [path]/global.php(407) : eval()'d code on line 429
Could not connect:

The line is a $db call. I've updated the database setting in config.php but it appears $db still has the old server name in it. How do I clear/rewrite that variable? __DEFINE_LIKE_SHARE__
